Why Do 9v Batteries Suck?

So the modern practical uses for these are in guitar effects, alarm clocks, and smoke detectors. leave your effects on and they die in a couple of hours. as a backup to your alarm clock, it dies in four or five hours (not even powering the LCD). i have no idea how long these things last in a smoke detector, but my guess is the next housefire and i'm a dead man. why do these batteries suck so bad? why do we still use them? why hasn't science come up with anything better?
